class_docstr: A graph representation that works directly with the maxflow.GraphDouble graph as
  base. It is therefore less flexible as graph.Graph, but leads to lower memory
  requirements.
  
  The graph contains nodes, edges (directed) between the nodes (n-edges), edges
  between two terminals (called source and sink) and the nodes (t-edges), and a
  weight for each edge. 
  
  Notes
  -----
  The node-ids used by the graph are assumed to start with 0 and be
  continuous. This is not actually checked, so be careful.
  
  This wrapper tries to catch the most usual exception that can occur in the
  underlying C++ implementation and to convert them into catchable and meaningful
  error messages.
docstr: Get the nodes.
  
  Returns
  -------
  nodes : list
      All nodes as an ordered list (starting from 0).
